The information in this article applies to:

- Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 
- Microsoft Windows versions 3.1, 3.11 
- Microsoft Windows for Workgroups versions 3.1, 3.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you expand an MS-DOS program file with the Windows Expand utility, and then
execute the file from within Windows, one of the following error messages may be
displayed:

  This application has violated system integrity due to execution of an invalid
  instruction and will be terminated. Quit all applications, quit Windows, and
  then restart your computer.

  -or-

  Insufficient memory to run the application. Quit one or more Windows
  applications to increase available memory, and try again.

In addition, the icon for a Windows-based MS-DOS 6.0 utility may appear as a
generic MS-DOS icon.

CAUSE
=====

The Expand utility included with Microsoft Windows 3.1 or Windows for Workgroups
3.1 does not correctly expand MS-DOS 6.0 files. The Windows Expand utility only
copies the files from the MS-DOS 6.0 disk to the target directory; it does not
expand them.

NOTE: You may accidentally use the Windows Expand utility if the Windows
directory is in the path before the MS-DOS directory.

If a Windows-based MS-DOS utility is still compressed, its icon appears as a
generic MS-DOS icon, instead of its usual icon.

WORKAROUND
==========

To properly expand files from the MS-DOS disks, you must use the MS-DOS Expand
utility (EXPAND.EXE), which correctly expands MS-DOS files, as well as Windows
3.1 and Windows for Workgroups 3.1 files.

The MS-DOS 6 Expand utility (EXPAND.EXE) is located on Disk 1 of the 720-kilobyte
(K), 1.2-megabyte (MB), and 1.44-MB disk sets and on Disk 3 of the 360K disk
set. It can also be found in the MS-DOS directory if you have already installed
MS-DOS 6.0 or 6.2.
